Driver´s characteristics for map information representation (North up map/heading up map) in navigation displays

Driver characteristics for two kinds of map information representation (North-up map and Heading-up map) of in-vehicle navigation system (IVNS) are investigated. Field experiments and laboratory experiments are both conducted. The driver´s behavior is investigated by eye movement and subjective evaluation. The results imply that the driver´s visiblity is influenced by the cognitive characteristics of the driver, and that the map representation should adapt to the driver´s spatial orientation.
